# Quantitative Comparisons

In this section there are two quantities. You need to determine the relation between the two quantities.

1. m + e = 18

Quantity 1: 18

Quantity 2: m - e

1. Quantity 1 is equal to Quantity 2
2. Quantity 2 is greater than Quantity 1
3. No relation
4. Quantity 1 is greater than quantity 2

Explanation: As quantity 1 is 18 = m + e and quantity 2 is m - e, option (c) is the right answer

2. Column z = 3a + 9
Column p = 15
Assume that quantity 1 is (z) and quantity 2 is 15. Determine whether

1. Quantity 1 is greater than Quantity 2
2. Quantity 2 is greater than Quantity 1
3. Both the quantities are equal
4. The relationship between the two quantities cannot be determined

Explanation:  As quantity 1 = z = 3a + 12

= 3 (3) + 12

= 9 + 12

= 21 = quantity 15.

3. c is a negative integer

20/30 = c/b

Quantity 1: c/b

Quantity 2: 2

1. Quantity 2 is less than quantity 1
2. Quantity 1 is less than quantity 2
3. Quantity 1 is equal to quantity 2
4. No relation

Explanation: 20/30 = c/b

˝ = c/b

Therefore there is no relation between 1 and 2

4. a< 25 and h > 25

Quantity 1: ha

Quantity 2: ah

1. Both the quantities are equal
2. 1 is less than 2
3. 2 is less than 1
4. No relation

Explanation: ah = ha, therefore (a) is the right answer.

5. P = the number of hours in 10 days

A = the number of seconds in 6 minutes

1. A is greater than P
2. P is greater than A
3. There is no relation between P and A
4. P = A

Explanation: P = 10 x 24 =240

A = 6 x 60 = 360

Therefore G is not equal to A.

1. Quantity 1: (3/18)4

Quantity 2: (5/12)1/2

1. Quantity 2 is greater than quantity 1
2. Quantity 1 is greater than quantity 2
3. Both quantities are equal
4. There is no relationship between both the quantities

Explanation: (3/18)4 = 0.66; (5/12)1/2 = 0.2083

Therefore there is no relationship between both the quantities

6. E = 0.15

U = 0.19 / 3

1. E is greater than U
2. U is greater than E
3. E is equal to W
4. There is no relation between E and U

Explanation: U = 0.19 / 3 = -6.33, whereas E = 0.15.

Therefore E is greater than U.

7. 60 > c < 80, while 36 > k < 93

Quantity 1: c

Quantity 2: k

1. Value of quantity 2 is more than value of quantity 1
2. Value of quantity 1 is more than value of quantity 2
3. Values of both quantity 1 and 2 are equal
4. There is no relation between the 2 quantities

Explanation: As quantity 1 can be any number between 60 and 80, and quantity 2 can be any number between 36 and 93, option (d) is the right answer

8. 50 > i < 80, while 19 > e < 82

Quantity 1: i

Quantity 2: e

1. Value of quantity 2 is more than value of quantity 1
2. Value of quantity 1 is more than value of quantity 2
3. Values of both quantity 1 and 2 are equal
4. There is no relation between the 2 quantities

Explanation: As quantity 1 can be any number between 50 and 80, and quantity 2 can be any number between 19 and 82, option (d) is the right answer

9. I + 9A >10

Quantity 1: 10I + 6A
Quantity 2: 34

1. Quantity 2 is greater than Quantity 1
2. Both the quantities are equal
3. Quantity 1 is greater than Quantity 2
4. The relationship between the two quantities cannot be determined

Explanation:  I + 9A > 10

Hence, I > 10 - 3A

Multiplying by 3 to both sides of inequality,

9I > 30-9A

Hence, 10I + 9A > 34

Now Q1: 9I + 6A
